Definitions

  • the invention relates to a telescopic tube for a discharge device on a loading cart for coke ovens with a filling pipe, with a filling pipe surrounding the filling pipe, vertically adjustable outer tube, with a sealing arrangement for sealing the annular gap between the filling pipe and the outer tube, which encloses the filling tube has elastically deformable seal, and with a the seal acting tensioner which is a drive for operational tensioning and loosening, the Seal by tensioning the tensioning device against the filling pipe as well as against a flange surface connected to the outer tube is compressible and the seal by loosening the Clamping device is released from the filling pipe wall, see above that the outer tube is vertical without wearing the seal is adjustable.
  • Telescopic tube Feed trolleys for a modern coke oven operation equipped with a telescopic tube, which the coal from one located below a hopper Discharge device transferred to the coke oven chamber.
  • the Telescopic tube is formed in several parts and at least has a filling pipe connected to the discharge device and a lifting and lowering outer tube. Special value is in the execution of the telescopic tube on a tight Execution placed so that during the coal filling in the coke oven chamber no fill emissions through the telescopic tube get into the environment.
  • Known telescopic tube has the discharge device connected filling pipe at its lower end a ring-shaped collar filled with sand.
  • the known version allows it not, height differences between the lower edge of the lowered Compensate outer tube and the filling hole frame.
  • the cuff usually made of steel or one Special fabric made, has only a limited stretch, which are directly related to their overall length stands and neither by the constructive execution nor can be significantly influenced by the choice of material.
  • the Distance between the lower edge of the telescopic tube when raised Condition and the top edge of the fill hole frame often greater than the allowable expansion of the compensator, so that Entire furnace ceiling areas with the filling hole frames in complex and raised actions associated with significant costs and in the range of the allowable expansion joints have to be brought.
  • a telescopic tube with the features described above is known from EP-A 0 396 877.
  • the known version is an elastically deformable that surrounds the filling pipe Seal provided in one of two Flange rings limited and connected to the outer tube annular housing arranged radially from one in the tensioned strap is inserted into the housing.
  • the Drive of the clamping device has one of the ends of the Tensioning band pulling drawbar on.
  • DE-A 39 30 871 is a telescopic tube with a tubular Seal described that inflated with compressed air becomes.
  • the invention has for its object a telescopic tube of the intended purpose described at the beginning, that any distance between in a large work area the lower edge of the telescopic tube and the upper edge of the filling hole frame of a coke oven bridged and the leakage of Filling emissions effectively prevented.
  • the telescopic tube 1 shown in Fig. 1 is to the discharge device 2 of a loading trolley, not shown connected, on the oven ceiling 3 of a coke oven is movable.
  • the telescopic tube 1 has a Discharge device 2 firmly connected filling tube 4 and a the filling pipe 4 enclosing, vertically adjustable Outer tube 5 on. Via a support ring 6 and articulated rods 7 the outer tube 5 is connected to a lifting beam 8.
  • By Adjustment movement of the lifting beam 8 is the outer tube 5 a rest position shown in Fig. 1 can be lowered until the lower edge of the outer tube 5 on a filling hole frame 9 of the coke oven chamber to be filled.
  • a seal arrangement 10 which the annular gap between the filling pipe 4th and the outer tube 5 during the loading of the coke oven chamber seals with charcoal, prevents during the Carbon filling Filling emissions through the telescopic tube into the Environment.
  • FIG. 2 shows the structure of the seal arrangement 10.
  • You has an elastically deformable surrounding the filling tube 4 Seal 11 and one acting on the seal 11 Clamping device 12.
  • the clamping device 12 is with equipped with a drive 13 for operational tensioning and loosening.
  • tensioning the tensioning device 12 elastically deformable seal 11 against the filling tube 4 and against a flange surface connected to the outer tube 5 pressed.
  • loosening the clamping device the seal comes 11 free again from the filling pipe wall, so that Outer tube 5 raised without wear of the seal 11 or can be lowered.
  • the seal 11 can, as in FIG. 2 indicated, from several sealing rings arranged one above the other consist.
  • the seal 11 is in one of a flange ring 14 and a tubular section limited annular space arranged by a vertically adjustable connected to the drive 13 Clamping ring 18 acted upon in the axial direction.
  • the outer tube 5 for one Filling process lowered and the clamping device 12 clamped.
  • the seal consisting of several sealing rings 11 is by an actuating movement of the upper clamping ring 18 pressed and is under pressure both on the filling tube 4 and also on the corresponding contact surfaces of the outer tube 5 on.
  • the right half of FIG. 2 shows the sealing arrangement 10 with the clamping device 12 released.
  • the drive 13 is relieved, and the upper clamping ring 18 is free of pressure on the seal 11.
  • the elastic sealing rings have deformed back, with between the seal 11 and the lateral surface of the filling tube 4 a gap s can be seen is.
  • the outer tube 5 is vertically adjustable without wear the seal 11.
